vkCmdDecompressMemoryEXT

Decompress data between memory regions

To decompress memory containing compressed data, call:

void vkCmdDecompressMemoryEXT(
    VkCommandBuffer commandBuffer,
    const VkDecompressMemoryInfoEXT* pDecompressMemoryInfoEXT);

pub fn cmd_decompress_memory_ext(
    command_buffer: vk::CommandBuffer,
    p_decompress_memory_info_ext: *const vk::DecompressMemoryInfoEXT,
);

commandBuffer is the command buffer into which the command will be recorded.
pDecompressMemoryInfoEXT is a pointer to a VkDecompressMemoryInfoEXT structure describing the decompression parameters.

Valid Usage

The memoryDecompression feature must be enabled

commandBuffer must be a valid VkCommandBuffer handle

pDecompressMemoryInfoEXT must be a valid pointer to a valid VkDecompressMemoryInfoEXT structure

commandBuffer must be in the recording state

The VkCommandPool that commandBuffer was allocated from must support VK_QUEUE_COMPUTE_BIT, or VK_QUEUE_GRAPHICS_BIT operations

This command must only be called outside of a render pass instance

This command must not be called between suspended render pass instances

This command must only be called outside of a video coding scope

Host access to commandBuffer must be externally synchronized
Host access to the VkCommandPool that commandBuffer was allocated from must be externally synchronized
